Energy - GS네오텍은 사람을 먼저 생각합니다

  • ESS
  • UPS/LiB for rectifier
print

The secondary battery market is rapidly moving from lead storage battery, nickel-hydride battery and nickel-cadmium cell used frequently as secondary batteries to lithium-ion battery in order to overcome the limitations in weight, environment, and capacity and to achieve miniaturization and high capacity of battery for IT equipment and industries. In this regard, GS Neotek has secured various relevant solutions and business results from mobile carriers, IDC centers and university hospitals.

Comparison of LiB for UPS

  • Comparison of lithium-ion battery
    It has higher volume/weight energy density than other secondary batteries and saves weight and space with its excenllent charging/discharging characteristics
